PAPER CONTAINER.

Specification of Letters Patent.

' rateatea aan ir, ieiapplicaton filed June 21, 1916. Serial No. 104,847.

certain new and useful Improvements in Paper Containers, of which the following is a specification. l

The object of the invention is to provide a paper container commercially eflicient as a carrier of liquids, or solids, as a substitute' for glass or metal vessels.

The important features of such a container are that it shall be sulflciently strong for the service required of it; thoroughly sterile for a first using; and having a tight lid easily removable and reinsertible many times without destroying the efficiency of the container. l.

The form -of the bottom and its rigid attachment to the inside wall of the container is a distinct and important feature of construction; as is also thecorrect conical shape of the cup adapted to close nesting for convenience and commercial economy in storage and transportation.

These objects are reached in the manner hereinafter setl forth, reference being had to the accompanying drawings forming part of this specification, in which- Figure 1 is a view of a single cup;

Fig. 2 shows in cross wsection the shape and formation of the cups nested for packing and transportation;

Fig. 3 is a top view of a cup or container;

Fig. A: is a plan view of the flanged lid of the form preferably used;

Fig. 5 is an illustration `showing a carton ofcolumns of nested cups and Fig. 6 is a view of a single cup, showing same constructed of three ply material, the plies being designated as a1 a2 and a3.

Similar letters refer to similar VpartsA throughout the drawings.

In order that my invention may be reliably useful as a sanitary, economical container for carrying milk or 'other food products, I have endeavored to combine in the construction details that are vitally impor-` tant to high efficiency.

In making a paper container for a single service it is`important to use only the least quantity of paper and sterilizing material needed for the purpose of economy, to which matters of commercial necessity I have carefully adhered in working out my invention.

Referring to the drawings a is the body portion of the container., This container must 'be made from select paper, wound preferably three ply as illustrated in Fig. 6 and of such definite taper most suitable for close nesting and for securely holding the lids in place against accidental removal. lhere. in ust also be provision made against Jamming the cups too tightly together; that while fitting snugly Within each other they may be always easily separated without the lingers coming in contact with the inside thereof to -jeopardizeV their sterility.

As shown in Figs. l and 2 each container has a top c and a two piece bottom g, consisting of a top-flanged piece e and aring f of thicker material cut from a straight tube placed under the flanged part as a support. The supporting ring f is first inserted within the cup and pressed down even with the lower edge thereof; then cement is applied around the top edge of the ring and against the side wall of the cup and the flanged piece is inserted from above and pressed down firmly upon the supporting ring.

Thus my two piece bottom is securely connected to the cup wall against possibility of displacement by the weight of the material in the cup; or by the pressure of the nested cups above it. p

Thus I provide a solid column of heavy card board reaching from the lower edge of the bottom cup upward through the entire nest which leectually resists any force to jam the cups tightly together.

There are good reasons for applying a band or hoop b around the top edge of the cup to strengthen it against the outward pressure of the lid and to afford means for 'firmly holding the cup with the fingers for carrying purposes. This band or collar I) around the top of the containers is cut from a straight tube and cemented firmly in place during the process of manufacture.

" The uniform depth of nesting the cups is lowed to become thoroughly dry they are sterilized in a paraffin bath and immediately nested; each cup becoming a close lit` ting lid to the one belo\v,.while the top one is closed by a flanged lid as shown in Fig. 4.

Four columns of nested cups It are in- ',cl'osed in a sealed wrapper and nine of these packages with their complement of lids c, separately boxed, are inclosed in a sealed ear-tono', which makes a practical means for itorage and transportation in the most app'royed forni. Such a package only 2lx'2 l x22 Contains 500 quart size Containers.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

l. A paper container of tapering form adapted 'to be nested with other containers of like construction, having a two piece bottom consisting of a ring member below to support a flanged member resting` upon it, both secured to the inside wall of the conta mer forming a solid column of card board reaching from the bottom edge oi the container body upward to a point where another similar container may rest upon the upper edge ot' said bottom as a support.

2. A paper container made. with a body of tapering 'form adapted to be nested; ha\'- ing a bottom of two members eonsistnlg` ol' a. flanged top piece resting,r upon a' ring,- piece of suchheight that the combined members shall fill the space between the bottom edges of the walls of the nested containers to prevent excessively tight nesting.

In testimony whereof I aiix my signature in presence of two witnesses.
